Answer:
Step-by-step explanation:
Hello!
You have two populations of interest and want to compare them. If you define the study variables as:
X₁: average hourly wages of an employee of the Downtown store.
n₁= 25
X[bar]₁= $9
S₁= $2
X₂: average hourly wages of an employee of the North Mall store.
n₂= 20
X[bar]₂= $8
S₂= $1
Both samples taken are independent, assuming that both populations are normal and that their population variances are equal I'll use the Student's-t statistic with a pooled sample variance to calculate the Confidence interval:
95% CI for μ₁ - μ₂
(X[bar]₁-X[bar]₂) ± 
Sa= 1.64
(9-8)±2.017*
[0.007636;1.9923]
I hope it helps!
Answer:
9+10=21

Answer:
2 pieces.
Step-by-step explanation:
To identify how many pieces he can split with 8/10 of a candy bar, divide 8/10 by 1/3.
<u>Divide 8/10 by 1/3:</u>
<u>Find the Ricipricol, then flip the sign:</u>
<u>Multiply:</u>
<u />
2.4 represents how many pieces of chocolate he can make with 8/10 of a candy bar.
However, 2.4 pieces can't be made, therefore he can only make 2 <u>full</u> pieces.

27 is my answer
Math:
7 dogs, 3 cats, 5 birds. In total, there are 15 animals all together.
So ignore the 3 and 5 those are in there to throw you off. To get the percentage, you do 7/15
So you'd get 0.4666667
Answer: 0.467
Rounded Answer: 0.47 (Or 47% B)
